you know, I could really actually easily see this as a move canon would do. when they announced the specs for the mk3, they also made it known that the mk2 would be continued until end of 2012. With the cost and spec sheet of the mk3, taking that around $2000 camera off the scene would be a blow. And if nikon is doing a around $2000 FF, what better way to revamp the 7D. Lots have said the only issue with the 7d was that its 1.6 crop (of course, those in wildlife would disagree). For those in studio, wedding, and fine art though a good FF cam in the 2K price range would be awesome. More times than not, the 7D is compared to the 5d2, and vice versa. In fact, many 5d2 users love the IQ, but wisdhed for the functionality of the 7D, and many 7d users have wanted a FF 7D (basically for the AF and fps). Now we have the mk3, which I think is a pretty badass camera, with an AF system that is far better than the mk2. I got my first taste on one last night. The quality of the shots I saw on it at ISO 128,000 with no flash ...frankly WOW, better than what I see out of my 7D at 4000-6400 with flash. So the mk2 crowd should be way pleased (unless you never shoot in low light!) But that leaves all of those folks on a 7D wondering whats next, save for the mk3?
That's where I think a FF 7D makes a lot of sense....
make it awesome enough to bring the 7d crowd in, while not cannibalizing mk3 sales:
Dual digic 5+
one CF card slot
FF sensor 18 MP
ISO range 100-128,000 (1 stop shy of mk3)
21pt AF (same as current 7d)
That would make for a solid backup to the mk3 for wedding shooters. That would also make for a really nice upgrade for current 7D users. It kind of would be the camera everyone wanted to see in the mk3 (actually, the cam we wanted before the mk3 and the d800 became a reality - now there will be - I want MP and dynamic range whining, but, before the mk3 and d800 was announced, people wanted nothing more than the 7D AF with a 5d sensor...)
if the specs for the new T4i are any indication of whats next, its really hard to find a spot for the 7d. I am suspecting the 70d will be improved enough to take the 7d's place as the king of crop sensor for canon.
The only other direction I could see for the 7D is this:
fill in the rest with whatever...
